Application filed Key 23. 1906. v Serial 110.318.405.

apparatus for cleaning sacks, more particularly cement-' sacks.

Its object is .to provide for accomplishing that purpose both by mechanical means and the action of compressed air delivered into the sacks; and to promote simplicity and economy in the manner of carrying out the same, as well as to perform the cleaning action in the minimum time and with effectiveness.

Said invention consists of certain features substantially as hereinafter fully disclosed and specifically pointed out by the claims.

In the accompanying drawings illustrating the preferred embodiment of my inventionFigure 1 is a view showing principally a gang or number of sack holders and heaters in edge elevation, characteristic of said invention, a sack appearing in dotted lines in position upon one of the heaters for cleaning. Fig. 2 is a view also in elevation taken at right-angles to the view-point of Fig. 1, a sack in like manner being also represented upon the only beater disclosed by this view. Fig. 3 is a broken detached enlarged view of one of the holders or frames and boaters proper carried thereby. Fig. 4 is an enlarged detailed view showing more especially one of the beater spring thrusting connections or joints. Fig. 5 is a vertical section of one of the heaters. Fig. 6

' is an enlarged detailed sectional view showing more clearly the collar at the point of conjunction between the air-receiving pipe and its carrying shaft, together with the -air-inlet nozzle for connection with a hose leading from a compressed-air source of supply.

In the disclosure of my invention, 1 suitably mount in position upon suitable timbers or supports 1, transverse rock-shafts 2 having their tubular bearings 3, secured to said timbers, and said shafts are suitably equipped with arms 4, preferably sleeved and keyed thereon as at 5, 6 to stand vertically, and are themselves provided near their extreme upper ends with lateral pins or studs 7, the action of which will presently be seen.

' Suitably carried and actuated by the rock-shafts 2, are upright frames or holders 8 for carrying or holding the sacks to be cleaned, an example of which being disclosed by dotted lines in Figs. 1 and 2. Each frame or holder comprises preferably vertical lateral rods or bars 9 whose lower ends are suitably secured to their respective rock-shafts 2 and their upper ends connected to, and bearing a hollow or tubular member 10,

" which, for convenience, is composed of a number of tube or pipe sections and centrally depending from,

and communicating with which is a pipe 11, opening into, and having screwed thereon at its lower end a coupling or collar .12 keyed or otherwise held upon said shaft passing transversely therethrough. The horizontal or connecting tubular member 10 between the lateral bars or members of each sack-carrying frame or holder is provided with numerous apertures a, a for the delivery of the compressed air or blast into the sack for utilizing the same in aiding the elimination of particles adhering to the sack and the dust thus created therefrom. The collar or coupling 12 has produced therein a laterally opening diagonal passage 13 also opening into the lower end of the pipe 11 and into said passage is screwed a nozzle 14 to which, in prac tice, is-to be applied one end of a hose or pipe (not shown) leading to a suitable supply or source of com-' pressed air for deliveryinto the pipe 11 and finally into the sack for aiding the cleaning thereof as will be readily appreciated. Said sack holders or frames are each provided or equipped with preferably duplicate beaters 15 arranged upon opposite sides of the pipe 11, for mechanically aiding the cleaning operation or agitating the sacks. Each beater or agitator comprises two stud-bolts 16 the lower one passing transversely through a shaft 2 and the upper one passing transversely through the pipe or'tubemember 10, and in-.

termediate pieces 17 secured or clamped transversely to,

and upon opposite edges of eye-bars 18. Said eye-bars are connected to links 19, 20, the link 19, in turn being connected to the upper stud-bolts 1G and the link 20 passing through the upper end bar of a preferably rectangular or frame member 21 of what may be termed an endwise-thrusting connection or joint 22 articulated or pivotally connected to the lower stud-bolts 16. The other member of said joint or connection 22, in the form of a preferably coiledspring 24, is arranged upon the nut-equipped lower end-portion of the link 20, within said rectangular or frame member 21, said spring exerting its stress or tension upon the nut and said frame-member. This arrangement provides as is apparent, for additional flexing movement of the heaters, accordingly for a greater or extended length of stroke, whereby a more effective beating action is obtained, especially as is required in certain kinds of work. Said intermediate pieces 17 have secured thereto and carry at their ends longitudinal bars 25 adapted to engage or operate upon the sack throughout its length as the sack-carrying frame or holder is actuated by the swinging or oscillating motion thus imparted to said bars, out of the plane of the sack-car- 'rying frame or holder for the effective cleaning of the sack or detaching adhering material therefrom which, as already stated, will be aided by the current of compressed air delivered into said sack or sacks. A suitably driven second shaft 26 is supported or journaled in position, in a plane above that of the shaft 2 and at v ing a beating action upon the sacks supported in posioperating upon the suck, a grooved cam equipped shaft for rightangles thereto, upon preferably right-angled bracket-castings 27 having their lower portions each forming an additional right-angle to conform to and rest upon the upper surface of one of the timbers 1, to which it is suitably bolted. Said shaft 26 is provided with a number of grooved cams 28 whose grooves receive the pins 7 of the shaft-anus 4 and accordingly provide, as said shaft is driven, for rocking or oscillating the shaft 2, thus imparting a corresponding motion to the sack-carrying frames and the heaters for delivertlon as aforesaid.

A dust-receiving pan or chute 29 is suitably arrange and held in position immediately under the sacks, the open ends ot the latter depending contiguous to the upper edge of said pan to permit the ready reception thereinto of the dust and other adhering particles detached from said sacks.

A suction-pipe 30 is suitably arranged directly below and in line with the vertical longitudinal center of the dust-receiving pan or chute 29, the latter being adapted to deliver its contents through a longitudinal central opening in its bottom into said suction-pipe as is apparent particularly from Fig. 2. Said pipe has arranged at its delivery end an exhaust fan (not shown) for creating a suction therein for the thus suitable withdrawal of the dust &c., irom said pipe as will be readily understood.

I claim 1. A machine of the character described, comprising a frame or holder adapted to permit the inversion of a. sack thereover, an agitator or heater carried by said holder for engaging and actuating said holder and agitator, and means for operating said shaft.

2. A machine of the character described, comprising an oscillating frame or holder adapted to permit the inversion of a sack thereover, an agitator or heater carried by said holder for operating upon said sack, and means for actin ating said holder and heater or agitator, said frame or holder embracing hollow or tubular members having apertures for delivering compressed air into said suck for aid ing the removal of adhering particles and dust therefrom.

3. A machine of the character described, comprising a rock shaft carrying an upright frame or holder adapted to permit the inversion thcreover of a sack, an agitator or heater connected to said frame and actuated by said rock shaft and adapted to operate upon said sack and a camcquipped shaft for actuating said rock-shaft said frame or holder embracing tubular or hollow members equipped with apertures for delivering compresed air into said sack.
